RX Multicast Queue Full

Hello.

I got "RX Multicast Queue Full" messages in the log of my 5508 WLC for more than a week now and have problems with client association.

The multicast mode on the controller is set to "Unicast".

Can anybody tell me what the problem could be?

Thanks.

Re: RX Multicast Queue Full

You can search the forum and others in the past have had the same issue, but it wasn't client impacting. If it's client impacting, then maybe your best off opening a TAC case. Also, make sure you also post the WLC model, firmware and access point type as that helps also.

Re: RX Multicast Queue Full

Sorry for the lack of information.

The controller is a 5508 running software version 7.3.101.0.

The access points are a mix of 1240 and 2600 series access points.

Actually, the impact is not as big as there is a need to open a TAC case.

I don't even really know if the problem with the clients connectivity is related to the multicast queue, but it started at about the same time.

There are no arp storms or anything I could read in an older discussion.
